This Titanium code can be used in an appcelerator project (with Hyperloop enabled) to determine if an iOS advertisement was the cause of the current installation

appc.js

module.exports = {
  hyperloop: {
    ios: {
      xcodebuild: {
        frameworks: [
          'iAd'
        ]
      }
    }
  }
};

titanium_ios_ad_attribution.js

var ios_ads_attribution_requested = Ti.App.Properties.getBool('IOS_ADS_ATTRIBUTION_REQUESTED', false );
if(!ios_ads_attribution_requested) {
  var ADClient = require("iAd/ADClient");
  ADClient.sharedClient().requestAttributionDetailsWithBlock(function(attributionDetailsDictionary, errorNsError){
    if(errorNsError != null){
      if(errorNsError.code == 0){
        console.log("ADClientErrorUnknown");
      } else if(errorNsError.code == 1){
        console.log("ADClientErrorLimitAdTracking");
      }
      console.log("ADC error: " + errorNsError.description); // I haven't tested this yet
    } else {
      var data = String(attributionDetailsDictionary);
      if(data != null || data.length > 0){
        // Save #data
        // Note: 
        // This isn't a valid JSON structure. Here is the server-side ruby I used to extract the campaign name:
        //   campaign_name = data.split("iad-campaign-name").last.split("\;").first.split("=").last.strip rescue nil
      }
    }
  });
  Ti.App.Properties.setBool('IOS_ADS_ATTRIBUTION_REQUESTED', true);
